FRANK ACHILLE IBIENVENU, 0F MONTREAL, QUEBEC, CANADA, ASSIGNOR, BY MESNE ASSIGNMENTS, TO CATELLI MONTREAL, CANADA Application filed July 30,

The invention relates to a can heating device, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially of the novel features of construction pointed out in the claim for novelty following a description containing an explanation in detail of an acceptable form of the invention.

The objects ofthe invention are to re-- chine that will be of material assistance in preserving foods for transport and storage and at the same time economize in so far as the expenditures for labor and the generation of heat are concerned.

In the drawings, Figure 1 is a longitudinal sectional view of the machine.

Figure 2 is a cross sectional view on the line 22 in Figure 1 showingthe feed end.

Figure 3 is a perspective detail of the shower member.

Figure 4 is a perspective detail of the draining table.

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings, the standing frame 10 forms a support for the box 11 from which the legs 12 extend to said standing frame and to which they are adjustably secured.

The box 11 contains the inclined angle iron tracks 13 and 14 supported in the de sired positions on the brackets 15 and 16 which are rigidly secured in the interior of the'box in pairs and slotted at 17 for the pins 18 that hold the tracks to their adjusted position according to the sizes of the can passing therealong. v

The shower member 19 is formed of a pipe 20 formed in substantially U-shape and having an inlet pipe 21 from the closed end of the U connected to a steam supply pipe 22 MACARONI PRODUCTS CORPORATION LIMITED, OF

7 having" the valve 23 introduced therein and extending to a steam plant.

One leg of the U is inwardly turned at the'extr'emity and forms the steam nozzle 24 adapted to-spurt steam on the cans rolling along the tracks 13 and 14. Another nozzle 25, projects below the tracks and spurts upwardly. There are two more of these lower nozzles 26 and 2 7" and two more overhead nozzles 28 and 29 as well as two side nozzles 30 and 31, thus there are steam jets completely surrounding the cans and therefore the cans rolling down the tracks are bound to be liberally showered with steam, which condenses and is drained from the box.

The shower member is heldiat one end the other end by the steam supply pipe 20. The chute 33 is at the elevated end of the inclined tracks and leads thereto from the heading machine, so that when the cans by the bracket 32 from the tracks and at leave the latter, they slide down the chute on to the tracks where they roll by gravity under, over and beside the jets of stem, thereby becoming thoroughly heated after the temperature has fallen during the opera tions of filling and heading.

The cans roll on to the delivery and draining table 34, where the condensed steam "in the form of water drains to the central holes 35, from which it fiows to the spout 36. The table 34 is also adjustable as to height and is supported in the standing frame 37 permanently resting on the floor. T

This machine is preferably used as a step 7' in a canning process, though it may be more generally used.

' In this process of baking and canning pork and-beans after the pots leave the oven they are emptied into a bowl, the food has a chance to drop in temperature a little before the cans are filled and closed, however this is more beneficial than otherwise, still to maintain the flavor and insure absorption it is advisable to heat again before sterilization and this heating may be done as described by steam or by slight changes by electricity or gas.

It is most essential to provide a receptacle that will not cook the beans, as that has i been done already in the oven, but in the filling process the temperature has gone down and they are not in proper condition for sterilization because of that drop there fore a space is furnished where a spray merely restores temperature practically in Y the open air as the shield 38 on the top is merely a deflector partially closing in the box.

A can heating device comprising a box having an opening through the top at the inlet end, and an outlet at the other end, hangers formed of slotted bars and adjustable transverse rails, a can trackway supported on said rails at a chosen level and inclined, a steam feed pipe connected to a suitable source, a spray member having transverse, parallel, longitudinal and vertical pipes carrying nozzles directed upwardly, downwardly and sideways and adjustably mounted and supported by said steam feed pipe, and a draining table at said outlet from said box.
